The major bottlenecks will be the speed at which Interbase returns data and the network. 主要的瓶颈将是Interbase返回数据和网络的速度。 Spoon won't be a major hurdle. 勺子不会成为主要障碍。 If you see it running slowly you may want to install and run locally, in the same host as interbase and at least it won't have network speed to deal with. 如果看到它运行缓慢，则可能要在与interbase相同的主机中本地安装和运行，至少它没有网络速度。
But in the end, if the query is slow there's not mucj you can do from PDI side. 但是最后，如果查询速度很慢，那么您可以从PDI方面进行操作。
To run from the command line you can use pan.sh/pan.bat to run transformations or kitchen.sh/kitchen.bat to run jobs. 要从命令行运行，可以使用pan.sh/pan.bat来运行转换，或使用kitchen.sh/kitchen.bat来运行作业。
